Flat disk shaped collision

hey guys,
as the title says I have a flat disk that I am trying to use as a projectile, I was wondering if there was a way to create suitable collision for it, I had intended to use sphere collision and scale it down in the Z but it appears you can only scale sphere collisions uniformly.

many thanks

You’ll need to use Auto Convex Collision or create your own collision box in your modeling program and import that.

Alternative to what Jacky said - Use a Cylinder collision instead its still round, but you can control the height.
